Speed Modeling round #2

I love snowy, icy weather and wanted to do some landscapes representing that but not with a traditional look. I thought of isolation, remoteness and possibly an earth type planet when came I up with these.
I modeled the terrain in Sketchup, rendered in Keyshot, and used a Dutch Skies HDRI for my sky image which I then "surrealized" and painted over in Photoshop. All modeling and images from start to finish took about 2 hours.
Working on TRON: Uprising, I have also been inspired by Alberto Mielgo's graphically inclined backgrounds for the show.
